IMPROVEMENT IN SEATING FOOT-VALVES IN PUMPS.

Specification forming part of Letters Patent No. 195,153, datedSeptember 11, 1877; application filed March 3, 1877.

means for accurately reaming the seat preparatory to seating thevalve-box, and to accurately seat the latter in position; and to thisend it consists in two short nipples screwed onto the lower end of arod, and coupled by couplings which fit the bore of the pipe and serveas guides. The projecting end of the lower coupling is threaded toreceive a screw-shank on a reamer that reams the seat in the well forthe tapered valve-box, which has also a screw-shank to attach it to therod while being seated, after which the rod is unscrewed from it,leaving it in position.

Figure 1 is a vertical section of the lower end of a tube-well, showingthe valve-box seated. Fig. 2 is a sectional elevation, showing the toolsfor and manner of reaming out the valve-box seat. Fig. 3 is an elevationof the rod with the reamer screwed on. Fig. 4 is a vertical section ofthe well and tool, showing the manner of seating the valve-box.

1n the drawing, A represents the lower end of a tube-well, whose lowerextremity is perforated to admit the water. The walls of this perforatedend are made thicker than the rest of the tube, reducing that part ofthe bore, leaving a shoulder, B, at the top, in which to seat a taperedvalve-box, D.

The tube-well is driven in the usual way, after which the seat B isprepared to receive the valve-box by a reamer, 0, having the same taper,and a screw-shank, by which it is fastened to the end of acoupling-socket, a, at the end of a short nipple, c, which is coupled toa similar one by a like coupling, 1), and which upper nipple 0 isscrewed onto the lower end of a light rod or tube, E. The couplings a bfit snugly the bore of the well, so that when sent down and rotated thereamer will be guided by them in the axis of the well while reaming atapered seat at the shoulder B, after which the tool is withdrawn, thereamer removed, and the shank of the valve-box D is screwed into thesocket-coupling a. The valve-box is then lowered into the tube andguided fairly into its seat, when a few taps on the top of the tube Esets it fast, after which the tube E is unscrewed from the valve-box andwithdrawn from the well.

What we claim as our invention is-- The socket-couplings a b and nipplesc c, in combination with the tube E, for guiding a reamer in forming aseat for a valvebox, D, and for guiding the latter into its seat,substantially as described.
